Fachgebiet Chair for Computer Aided Medical Procedures & Augmented Reality | campar.in.tum.de Augmented Reality Wrong Assistance System Behavior - 1 � Ever driven a car with cruise control? � Did you take the foot off the gas pedal? � Did a slower car then pull on your lane? � You startled? � You hectically moved you foot from somewhere to the brakes? 2 CAMP-AR | Department of Informatics | Technische Universität München | 13 November 2007

Fachgebiet Chair for Computer Aided Medical Procedures & Augmented Reality | campar.in.tum.de Augmented Reality Wrong Assistance System Behavior - 2 � Ever driven a car with Adaptive Cruise Control (ACC)? � Did you take the foot off the gas pedal? � Did a slower car then pull on your lane? � Did the ACC turn off instead of braking? � You startled? � You hectically moved your foot from somewhere to the brakes? � What happened? � You were taken out of the loop � The assistance system showed a different behavior than the human driver 3 CAMP-AR | Department of Informatics | Technische Universität München | 13 November 2007

Fachgebiet Chair for Computer Aided Medical Procedures & Augmented Reality | campar.in.tum.de Augmented Reality Traffic Scenario Development � The delta between a assistance system‘s behavior and human behavior must be minimized � Early testing of behavior in VE � Problem: How to get realistic traffic scenarios? � My Approach: Tangible car on table-top 4 CAMP-AR | Department of Informatics | Technische Universität München | 13 November 2007
